TOALL WHOM IT MAY CONCERN:

Be it known that I, JAMES W. PATTERSON, of the city of Cincinnati, and State of Ohio, have invented a new and useful Device for Cooking; and I do hereby declare that the following is a full, clear, and exact deseriptioniof .the construction aud'operation of the same, reference being had to the accompanying drawings, and the letters of reference marked thereon. 4

My invention consists in cooking by steam in several vessels that are placed one above the other in the form of s. column, and each vessel having a. close-fitting cover. The diiference between this and other modes of cooking is that the steam cooks the food without coming in contact with it, whilst inother arrangements the vapor commingles with and passes through the food being cooked. Also, I so construct these cooking-.vessels that a perfect steam-chamber surrounds them on all sides, so that the heat visequally distributed to every part of the vessel.

My invention also consists in attaching to the bottom of the boiler a coil'oi` pipe, insuch a manner; as to leave one end of the pipe submerged in the water to supply the coil, whilst the other end passes -to the surface ofthe water, and conducts the steam generated in that partfof the coil below the bottom lto the chamber in the boiler above the water. A

Ido not use the coil specially to increase the heating-surface of the boiler, butA use it for generating steam, it heatingit more intensely; and thus its expansion forcibly passes it through the long pipe, and circulates it around the covered cooking-vessels above. l i l Toenable others to make and use my invention, I will .proceed to describe its construction and operation.

The outer part of the vessels may be constructed of metallic substances orwood, and the inner vessel of metal, or oi' earthen or porcelain material. V i i .Figure 1 represents the column, with several cooking-vessels attached or resting upon the boiler.` N, M, Z, G, and F are the cooking-vessels; E represents the boiler-vessel, with coil attached to its bottom; K representsthe coil of pipe which generates the steam. In g. 2,` the dotted lines `on the vessels F, Ste., represent the inner closed vessels as suspended in the cylinders, in which material to be cooked is placed,`and form the inner cylinders.

Figure 2`l represents an inside view of the boiler. P is the long end of the-pipe, which passes,A upto near the top of the boiler, with open side cap attached; S, the short end of the pipe, which supplies the coil, and has the weten-gauge cap attached; D is the top cover to the top vessel; R is the close orinner cover; d is the handle, covering a perforation on the centre; H is the inside view ofthe close cover; L is'the perforation.

u Figure 3. A represents the boiler, resting on its, side, presen-ting its bottom; K represents the coil= attached to the bottom; B represents the top and inside view of the `cooking-vessel, showingV the steam-chamber holes,`

through which thesteam passes from one vessel to the other Crepresents the top rim, connecting the outer and the inside vessels with the steam-Holes through the rim; P, in the boiler, in iig. l, represents the steam-` pipe, with open clap, which conducts the steam from the coil to the surface of tho waterline; J represents the water-line or surface, as represented by the dotted line; S represents the short end'of the coil submerged in Water, with the gauge-cap attached,` through which the'waterpasses to supply the coil. A

The operation ofthe device above described will be'readily understood without further detailed description.

Having thus described the nature of my invention, what I claim herein-as new, and desire to secure by Letters Patent, ,is-r

1. I claim the suspending of a seriesoi` cooking-vessels, having imperforate'd bottoms and sides, and provided with close covers, in an upright column or series,` in such a manner las to form steam-chambers above, below, and around each, as and for the purposes substantially set forth. I

2. I claim the steam or Water-coil K, provided withtshield?, and cap S, when used in connection with tho boiler E, in the manner and for the'purposes set forth. f

3. In each of a series of cooking-vessels, arranged substantially as shown,and used in connectionv with the boiler, I claim the chamber formed between the close sides of the inner and outer cylinder.` i

4. I claim the combination of the series of cooking-vessels N, M,v&c., with the 'boiler E, the whole made substantially as described, and s'o as tooperate in the manner set forth.
